Current through 2024-38, September 18, 2024

A. The requirements of Section 4 shall apply to all regulated VOC emitting processes that employ add - on control devices subject to Chapter 123, Paper Coating or graphic arts regulation except as provided below.

B. If a source installs a PTE that meets the specifications in Procedure T, and which directs all VOC to a control device, the capture efficiency is assumed to be l00 percent, and the source is exempted from the requirements described in Section 4. This exemption does not exempt a source from performance of any control device efficiency testing required under these or any other regulations. In addition, a source must demonstrate all criteria for a PTE are met during the testing for control efficiency.

C.If a source uses a control device designed to collect and recover VOC (e.g. carbon adsorber), an explicit measurement of capture efficiency is not necessary if the conditions given below are met. The overall control of the system can be determined over a 24 - hour period by directly comparing the input liquid VOC (L) to the recovered liquid VOC. The general procedure for use of such a control device is described in 40 CFR 60.433 with the following additional restrictions:

(1) The source must be able to initially equate solvent usage with solvent recovery on a 24 - hour (daily) basis, rather than a 30 - day weighted average as described in 40 CFR 60.433. Thereafter, the source must equate solvent usage with solvent recovery over another time period as deemed acceptable by the Department not to exceed 30 days. This demonstration must be done within 72 hours of the required time period over which the demonstration is to be done. Any recovery rates as calculated with the above procedure less than that needed to comply with the applicable regualtion shall be reported to the Department within 7 days.

(2) The solvent recovery system (i.e., capture and control system) must be dedicated to a single process line (e.g., one process line venting to a carbon absorber system), or

(3) If the solvent recovery system controls multiple process lines, the source must be able to demonstrate that the overall control (i.e., the total recovered solvent VOC divided by the sum of liquid VOC input to all process lines venting to the control system) meets or exceeds the most stringent standard applicable for any process line venting to the control system.
